The status bar at the bottom of the screen has two areas: On the
right, the status of each screen, and on the left, last activity
indicator.

Screen Status
-------------
The status bar shows the status of all 7 screens. Each one will appear
as one of:

- Grey dot (.): Screen not in use (never opened, or has been closed).

- Grey number: Screen has no activity since you last looked at it.

- Dark green number: Screen has new activity, but not channel text.
  Examples: join, part, nick change messages. Also server messages
  (numerics) in the [server] screen.

- White number: Screen has new channel text in it (but your name
  was not mentioned).

- Red number: Screen has activity that's intended for you: a private
  message, or your nick has been mentioned in a channel (AKA you've
  been highlighted).

Note: the colors listed above can be changed in the Config tool or via
the /color command.

When a number is displayed, you can press Start and that number to
switch to that screen. Trying to switch to an unused screen won't
do anything.

When switching screens with Start+A, FujiNetChat goes to the
right-most (highest numbered) highlighted screen (red). If there
are no highlighted screens, it goes to the right-most active screen
(white). If there are none, it looks for the right-most dark green
one. If there are no screens with activity, it doesn't change
screens.

This works about like irssi's Meta-A key, except that irssi actually
keeps track of when each of its windows became active or highlighted,
and goes to the oldest one first. FujiNetChat just starts at the last
screen and works its way down.

Note that the current screen (the one you're looking at) will always
be grey.

Activity
--------

This is a two character indicator. It shows network activity, and what
type of IRC message was most recently received.

The first (left) character:

Character | Meaning
----------+------------------------------------------------------------
  ! (red) | You're not connected to the server.
 up arrow | Sending data to the server.
down arrow| Receiving data from the server.
   blank  | Connected, but idle.
----------+------------------------------------------------------------

Second character:

Character | Meaning
----------+------------------------------------------------------------
    #     | Last msg was channel text.
    M     | Last msg was a private message to you.
    J     |     .... was someone joining a channel.
    P     |                 .... parting (leaving) a channel.
    Q     |                 .... quitting IRC.
  blank   | Idle, or none of the above (e.g. nick or mode changes).
----------+------------------------------------------------------------

The last message indicator will disappear after a few seconds of idle
time, or when you switch screens.
